Description: Anritsu MT8212A Cell Master, 25 MHz to 4000 MHz, Built-in DTF, Built-in Spectrum Analyzer, 10 MHz to 3000 MHz, Built-in Power Meter, 10 MHz to 3000 MHz, Built-in T1/E1 TesterThe Anritsu MT8212A spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Anritsu MT8212A. The CRT displays received signal strength (y-axis) against frequency ( x-axis).Some applications for Anritsu MT8212A Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Anritsu MT8212A spectrum analyzer to verify
